  "textContent": "To assess how small a macOS VM could be, I ran the same VM of macOS 26.4.1 on progressively smaller CPU core and memory allocations, using my virtualiser Viable. The VM’s display window was set to a standard 1600 x 1000, and I ran Safari through its paces and performed some lightweight everyday tasks, including Storage analysis in Settings. Starting with 4 virtual cores and 8 GB vRAM, where the VM ran perfectly briskly with around 5 GB of memory used, I stepped down to 3 cores and 6 GB, to discover that memory usage fell to 3.9 GB and everything worked well. With just 2 cores and 4 GB of memory only 3.1 GB of that was used, and the VM continued to handle those lightweight tasks normally. ↫ Howard Oakley This is good news for people interested in the MacBook Neo who may also want to run a macOS virtual machine on it.",
